viewing at 100% = what print size

OK so I am a math, what's the opposite of genius? Ahh moron. I digress. I have a question regarding "pixel perping" my dear friend my a77.

So I am shooting full 24mp photos and viewing on a 1920x1080 full HD 24 inch screen.

I have always wondered if I were to print this full 100% view off, what would the size be. I am sure there may be different variables but just a straight 24mp 100% screen view on a 24 inch screen. I thank you kind folks!!!!! And shoot your SONY'S
